So how do you surprise someone who’s turning 30 in a few days and has a national TV show?

Well, if you’re the mom of “Last Call” host Carson Daly, you fly in from California to surprise your son – by walking out on stage during tomorrow’s show (1:35 a.m./ Ch. 4). And you bring a cake while being joined by “competitive eater” Eric “Badlands” Booker. Musical guest Jewel also serenades Daly with a rousing rendition of “Happy Birthday” on tomorrow’s show, which also includes guests Cheri Oteri, Joey Fatone and Jack Hanna.

Daly, by the way, will co-host NBC’s “Macy’s Fourth of July Fireworks Spectacular” with Molly Sims (airing live from 9 to 11 p.m.) and will be roasted later this month in L.A. at “MTV Bash,” airing July 13 with Madonna, Britney Spears, Nelly, Jessica Simpson and many others.

Good lord! Kudrow’s thoughts on Julian

Most moms think their kids are special – but “Friends” star Lisa Kudrow is taking it to another level.

Kudrow, who graces the cover of In Style’s July issue, has this to say about her son, Julian, who’s now 5. “I don’t know if I should get a handle on this or not, but my husband and I honestly think he’s a superior being,” she says. “He’s godlike to me.” Therapy anyone?

Kudrow also says she feels a bit guilty about her work on “Friends,” which is ending its run after the upcoming season (and is paying its co-stars, Kudrow included, $1 million-per-episode for their sweat and toil).

“It feels like it’s rote now,” she says. “I’m afraid I’m not working hard enough.” But she adds that, “I don’t think you have to suffer to do things well. [Matt] LeBlanc told me, ‘You don’t have to work harder, it’s just second nature now.’ I think he’s right.”

Kudrow also says her interests outside of her family and work are . . . well . . . not much, really.

“I’m not passionate about art. And I’m not good at decorating, which is tough because Courteney [Cox] and Jennifer [Aniston] really are,” she says. “I’m not into fashion. Wow -I don’t do much, do I?”

“Trading Spaces” has spawned a boatload of imitators and knockoffs and is still going strong on TLC, which borrowed the concept from British television.

Last, but not least . . .

“Everybody Loves Raymond” star Brad Garrett will host Song Airways’ final “Song in the City” competition this Tuesday at the Supper Club. Finalists are competing for $25,000 and to win a red & white leather Coca Cola couch.
